SCHC-Project

SCHC communication protocol Python implemention based on the work of PySCHC, according to RFC8724 and RFC9011. This work consider the whole SCHC protocol (compression and fragmentation) applied to a real enviroment. It runs the communication between IPv6/UDP applications and a Smart Meter connected to a Raspberry Pi 3 over LoRaWAN. A second Node is used in order to evaluate the network accuracy.

This project was financed in part by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior – Brasil (CAPES) – Finance Code 001 and the companies Mux Energia and Fox IoT, by the R&D project ANEEL PD-00401-0005/2020.

Furthermore, the project was used in my undergraduate thesis in order to complete the Computer Engineer degree at Federal University of Santa Maria (UFSM) - Brazil.
